We carried out a study to evaluate the quality of results obtained by 14 nontechnical medical office personnel using desktop analysers. The instruments evaluated were the Reflotron analyser, the Seralyzer, the Vision analyser and the DT60 analyser. For precision studies low and high concentrations of control materials were used. For correlation studies the results obtained by the office personnel were compared with those obtained by a trained technologist. The coefficient of variation for the office personnel ranged from 3.0% to 8.1% with the Reflotron analyser, from 6.3% to 26.5% with the Seralyzer, from 1.0% to 4.1% with the Vision analyser and from 1.4% to 16.7% with the DT60 analyser. The correlation coefficient ranged from 0.970 to 0.997 with the Reflotron analyser, from 0.779 to 0.997 with the Seralyzer, from 0.975 to 0.998 with the Vision analyser and from 0.963 to 0.995 with the DT60 analyser. The proportion of results obtained by the office personnel that differed by more than 10% from those obtained by the technologist was 7% with the Reflotron analyser, 42% with the Seralyzer, 2% with the Vision analyser and 21% with the DT60 analyser. The instruments whose operation involves the least number of steps gave the most reliable results in the hands of medical office personnel.
我们开展了一项研究，以评估14名非技术医疗办公室人员使用台式分析仪所获得结果的质量。所评估的仪器有Reflotron分析仪、Seralyzer分析仪、Vision分析仪和DT60分析仪。在精密度研究中，使用了低浓度和高浓度的对照材料。在相关性研究中，将办公室人员获得的结果与经过培训的技术人员获得的结果进行了比较。使用Reflotron分析仪时，办公室人员的变异系数范围为3.0%至8.1%；使用Seralyzer分析仪时，变异系数范围为6.3%至26.5%；使用Vision分析仪时，变异系数范围为1.0%至4.1%；使用DT60分析仪时，变异系数范围为1.4%至16.7%。使用Reflotron分析仪时，相关系数范围为0.970至0.997；使用Seralyzer分析仪时，相关系数范围为0.779至0.997；使用Vision分析仪时，相关系数范围为0.975至0.998；使用DT60分析仪时，相关系数范围为0.963至0.995。办公室人员获得的结果与技术人员获得的结果相差超过10%的比例，使用Reflotron分析仪时为7%，使用Seralyzer分析仪时为42%，使用Vision分析仪时为2%，使用DT60分析仪时为21%。操作步骤最少的仪器在医疗办公室人员手中能给出最可靠的结果。
